Conclusions

The development of NLO calculations for a wide range of hadronic final state variables and the increasingly precise data from HERA, the Tevatron and LEP has provided a detailed testing ground for the strong interaction. At the DIS97 workshop, beautiful agreement of the data from LEPII with QCD was presented. At HERA and the Tevatron various chinks in the armour of QCD were identified. The detailed comparison of these data with the latest developments in the theoretical framework will determine whether the established paradigms are sufficient to understand the many facets of hadronic final state production reported at this workshop.
